我正在开始一个新的分布式项目。我应该使用SVN还是Git,为什么?
当前回答
SVN的2个主要优点很少被提及:
Large file support. In addition to code, I use SVN to manage my home directory. SVN is the only VCS (distributed or not) that doesn't choke on my TrueCrypt files (please correct me if there's another VCS that handles 500MB+ files effectively). This is because diff comparisons are streamed (this is a very essential point). Rsync is unacceptable because it's not 2-way. Partial repository (subdir) checkout/checkin. Mercurial and bzr don't support this, and git's support is limited. This is bad in a team environment, but invaluable if I want to check something out on another computer from my home dir.
只是我的经验。

我可能会选择Git,因为我觉得它比SVN强大得多。有一些便宜的代码托管服务对我来说非常有用——你不需要做备份或任何维护工作——GitHub是最明显的候选者。
也就是说,我对Visual Studio和不同的SCM系统的集成一无所知。我认为与SVN的集成会明显更好。
我从来没有理解过“git在Windows上不好”这个概念;我只在Windows下开发,git从来没有遇到过任何问题。
我绝对推荐git而不是subversion;它只是更加通用,并且允许“离线开发”,这是subversion永远无法做到的。它可以在几乎所有可以想象到的平台上使用,并且拥有比你可能使用过的更多的功能。

(摘录如下):
It's incredibly fast. No other SCM that I have used has been able to keep up with it, and I've used a lot, including Subversion, Perforce, darcs, BitKeeper, ClearCase and CVS. It's fully distributed. The repository owner can't dictate how I work. I can create branches and commit changes while disconnected on my laptop, then later synchronize that with any number of other repositories. Synchronization can occur over many media. An SSH channel, over HTTP via WebDAV, by FTP, or by sending emails holding patches to be applied by the recipient of the message. A central repository isn't necessary, but can be used. Branches are even cheaper than they are in Subversion. Creating a branch is as simple as writing a 41 byte file to disk. Deleting a branch is as simple as deleting that file. Unlike Subversion branches carry along their complete history. without having to perform a strange copy and walk through the copy. When using Subversion I always found it awkward to look at the history of a file on branch that occurred before the branch was created. from #git: spearce: I don't understand one thing about SVN in the page. I made a branch i SVN and browsing the history showed the whole history a file in the branch Branch merging is simpler and more automatic in Git. In Subversion you need to remember what was the last revision you merged from so you can generate the correct merge command. Git does this automatically, and always does it right. Which means there's less chance of making a mistake when merging two branches together. Branch merges are recorded as part of the proper history of the repository. If I merge two branches together, or if I merge a branch back into the trunk it came from, that merge operation is recorded as part of the repostory history as having been performed by me, and when. It's hard to dispute who performed the merge when it's right there in the log. Creating a repository is a trivial operation: mkdir foo; cd foo; git init That's it. Which means I create a Git repository for everything these days. I tend to use one repository per class. Most of those repositories are under 1 MB in disk as they only store lecture notes, homework assignments, and my LaTeX answers. The repository's internal file formats are incredible simple. This means repair is very easy to do, but even better because it's so simple its very hard to get corrupted. I don't think anyone has ever had a Git repository get corrupted. I've seen Subversion with fsfs corrupt itself. And I've seen Berkley DB corrupt itself too many times to trust my code to the bdb backend of Subversion. Git's file format is very good at compressing data, despite it's a very simple format. The Mozilla project's CVS repository is about 3 GB; it's about 12 GB in Subversion's fsfs format. In Git it's around 300 MB.
在阅读了所有这些之后,我确信Git是可行的方法(尽管存在一点学习曲线)。我也在Windows平台上使用过Git和SVN。
我很想听听其他人在读完上面的文章后会怎么说?
有趣的是: 我在Subversion Repos中托管项目,但是通过Git Clone命令访问它们。
请阅读在谷歌代码项目中使用Git进行开发
虽然谷歌代码原生说话 Subversion,可以轻松使用Git 在开发过程中。搜索“git” Svn建议这种做法是正确的 广泛传播,我们也鼓励你 用它来做实验。
在Svn存储库上使用Git给我带来了好处:
我可以分配到几个 机器,承诺和从 对他们来说 我有一个中央备份/公共svn存储库供其他人检查 他们可以自由地使用Git
这可以归结为:
你的发展是线性的吗?如果是这样,您应该坚持使用Subversion。
另一方面,如果您的开发不是线性的,这意味着您将需要为不同的更改创建分支,然后将这些更改合并回主开发线(Git称为主分支),那么Git将为您做更多的工作。
